Solving Complex Software Integration Challenges

The Problem

As systems grow, things get messy. Services stop talking to each other cleanly, migrations stall because nobody wants to own the risk, and the codebase becomes something people work around rather than with. These are the kinds of problems I find interesting.

How I Help

I've helped migrate legacy platforms to modern stacks, worked on PCI-compliant payment systems, and contributed to AI-powered products on tight timelines. I'm most useful when there's a complex technical problem that needs someone who can work across the full stack and keep things moving forward.
